Description

Technical Field

[0001] This utility model relates to the field of glue spraying machine technology, specifically to a glue spraying machine with positioning function. Background Technology

[0002] A glue spraying machine is a device that automates the application of adhesives using a program-controlled robotic arm. It is widely used in industries such as packaging, furniture manufacturing, electronics, and automotive. Its working principle is primarily based on pneumatic or electric drive, uniformly spraying liquid or hot melt adhesive onto the target surface. A servo motor and precision control system ensure the accuracy and consistency of the spraying. The equipment is typically equipped with a multi-axis linkage system, supporting X / Y / Z / U four-axis motion, featuring high positioning accuracy and integrating an intelligent touch interface and machine vision functions, automatically identifying the workpiece and generating a spraying trajectory. Glue spraying machines are divided into three main categories: pneumatic, electric, and hot melt, suitable for spraying low-viscosity, high-viscosity, and hot melt adhesives, respectively. They can handle various materials such as wood, metal, and plastic, significantly reducing adhesive waste and lowering labor costs. In the packaging industry, glue spraying machines are used for sealing and splicing cartons; in furniture manufacturing, they ensure a secure bond between boards and leather; and in the electronics and automotive fields, they are used for fixing and sealing precision components.

[0003] Chinese patent CN214021489U discloses a glue spraying machine, including a workbench. Each workbench has a support column on its top right side, a support plate on top of each column, and a hydraulic cylinder at the bottom of the support plate. A nozzle is located at the output end of each hydraulic cylinder. A mixing tank is located on the right side of the support column, and a motor is located on top of the mixing tank. A rotating shaft is located at the output end of the motor, extending through the bottom of the rotating shaft into the inner cavity of the mixing tank. Stirring blades are located on both sides of the rotating shaft. A feed inlet is connected to the top right side of the mixing tank. The glue spraying machine places glue into the mixing tank through the feed inlet. The motor operates, driving the rotating shaft to rotate, which in turn drives the stirring blades to rotate, thus stirring the glue. A liquid pump operates, drawing glue from the mixing tank into a suction pipe, which then transfers the glue to the liquid pump.

[0004] The glue spraying machine described in the aforementioned patent document sprays glue from a mixing tank onto the workpiece by placing a nozzle at the bottom of a hydraulic cylinder. However, the nozzle of existing glue spraying machines always points vertically downwards, making it impossible to spray glue onto the sides of the workpiece. Therefore, a glue spraying machine with a positioning function is proposed. Utility Model Content

[0005] To address the aforementioned problems, a glue spraying machine with a positioning function is provided. This machine utilizes multiple sets of electrically operated telescopic components to drive the glue spraying nozzle. The nozzle then moves a hemispherical limiting cover fitted onto the ball head, causing the hemispherical limiting cover to move along the center of the ball head. This allows for adjustment of the nozzle angle, solving the problem of the glue spraying machine's angle being unadjustable.

[0006] To address the existing technical problems, this application provides a glue spraying machine with positioning function, including a frame, a longitudinal slide table that can move longitudinally on the top of the frame, a horizontal slide table that can move horizontally on one side of the frame, a clamping mechanism on the upper surface of the horizontal slide table, and a material storage mechanism on the longitudinal slide table. The material storage mechanism includes a constant pressure cylinder fixed on the longitudinal slide table, a discharge pipe at the bottom end of the constant pressure cylinder, a connecting pipe inserted into the bottom end of the discharge pipe, and a ball head at the bottom end of the connecting pipe. The bottom of the connecting tube is equipped with a glue nozzle, and the top of the glue nozzle is equipped with a hemispherical limiting cover that can be fitted onto the ball head. The hemispherical limiting cover can rotate around the center of the ball head. The bottom of the constant pressure cylinder is also fixed with a limit frame. Electric telescopic components are installed at equal intervals around the bottom of the limit frame around its central axis. The end of the electric telescopic component away from the limit frame is hinged to the spray nozzle.

[0007] As one technical solution of this application, the top of the hemispherical limiting cover is fixed with a limiting ring to prevent it from falling off the ball head.

[0008] As one technical solution of this application, the clamping mechanism includes two fixed plates symmetrically installed on the upper surface of the horizontal slide table, and slide rails are symmetrically fixed on the fixed plates; The top of the fixed plate is equipped with a horizontally movable slide plate, and the bottom of the slide plate is fixed with a slider that slides in cooperation with the slide rail.

[0009] As one technical solution of this application, a hydraulic telescopic component for driving the horizontal movement of the skateboard is fixed on the upper surface of the fixed plate, and a pressure sensor for detecting the squeezing force of the skateboard is fixed at the output end of the pressure sensor, with the bottom of the pressure sensor fixed on the skateboard.

[0010] As one technical solution of this application, the sliding plate is provided with a horizontal mounting groove at the center of the side away from the slider. A rotatable bidirectional threaded rod is installed inside the mounting groove. Two sets of clamping rods for clamping the side of the workpiece are installed on the bidirectional threaded rod. The clamping rods are threadedly engaged with the bidirectional threaded rod.

[0011] The slide plate is also fixed with a servo motor for driving the bidirectional threaded rod to rotate, and the output end of the servo motor is rotatably connected to one end of the bidirectional threaded rod.

[0012] As a technical solution of this application, the side of the sliding plate near the mounting groove is symmetrically provided with a sliding groove for limiting the clamping rod; A limiting block is provided on one side of the clamping rod, which can slide along the slide groove.

[0013] The advantages of this utility model compared to the prior art are: This application utilizes multiple sets of electrically operated telescopic components to drive the glue spray nozzle. This allows the nozzle to move a hemispherical limiting cover fitted onto the ball head, causing the hemispherical limiting cover to move along the center of the ball head. This achieves adjustment of the nozzle angle, solving the problem of the glue sprayer's angle being unadjustable. Attached Figure Description

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. See Figures 1-6As shown, a glue spraying machine with positioning function includes a frame 1, a longitudinal slide 11 that can move longitudinally on the top of the frame 1, a horizontal slide 3 that can move horizontally on one side of the frame 1, a clamping mechanism 4 that is set on the upper surface of the horizontal slide 3, and a material storage mechanism 2 that is set on the longitudinal slide 11. The material storage mechanism 2 includes a constant pressure cylinder 21 fixed on the longitudinal slide 11. The bottom end of the constant pressure cylinder 21 is provided with a discharge pipe 211. The bottom end of the discharge pipe 211 is connected to a connecting pipe 212. The bottom end of the connecting pipe 212 is provided with a ball head 216. The bottom of the connecting pipe 212 is provided with a glue spray nozzle 213, and the top of the glue spray nozzle 213 is provided with a hemispherical limiting cover 214 that can be fitted onto the ball head 216. The hemispherical limiting cover 214 can rotate around the center of the ball head 216. The bottom of the constant pressure cylinder 21 is also fixed with a limit frame 22. The bottom of the limit frame 22 is equidistantly equipped with electric telescopic components 23 around its central axis. The end of the electric telescopic component 23 away from the limit frame 22 is hinged to the glue spray nozzle 213.

[0022] In use, the limiting frame 22 conveys the glue stored inside to the connecting pipe 212 through the discharge pipe 211, and then the connecting pipe 212 sprays the glue onto the workpiece through the spray nozzle 213. Multiple sets of electric telescopic components 23 work together to drive the spray nozzle 213. This allows the spray nozzle 213 to move the hemispherical limiting cover 214 fitted onto the ball head 216, causing the hemispherical limiting cover 214 to move along the center of the ball head 216. This allows for adjustment of the angle of the spray nozzle 213, solving the problem of the glue spraying machine's angle being unadjustable.

[0023] See Figure 5 As shown, the top of the hemispherical limiting cover 214 is fixed with a limiting ring 215 to prevent it from falling off the ball head 216.

[0024] By fixing the limiting ring 215 to the top of the hemispherical limiting cover 214, the limiting ring 215 is positioned above the horizontal center line of the ball head 216. The inner diameter of the limiting ring 215 is smaller than the diameter of the ball head 216, so that the limiting ring 215 can effectively prevent the hemispherical limiting cover 214 from falling off the ball head 216.

[0025] See Figure 3 As shown, the clamping mechanism 4 includes two fixed plates 41 symmetrically mounted on the upper surface of the horizontal slide table 3, and slide rails 42 are symmetrically fixed on the fixed plates 41. A horizontally movable slide plate 43 is mounted on the top of the fixed plate 41, and a slider 47 that slides and engages with the slide rail 42 is fixed on the bottom of the slide plate 43.

[0026] To ensure the stability of the slide plate 43, slide rails 42 are symmetrically fixed to the upper end of the fixed plate 41, and sliders 47, corresponding in number to the slide rails 42 and in sliding engagement, are fixed to the lower end of the slide plate 43. When the slide plate 43 moves, it can drive the sliders 47 to slide along the slide rails 42, so that the slide rails 42 and the sliders 47 cooperate to limit the slide plate 43, effectively ensuring the stability of the slide plate 43.

[0027] See Figure 3 As shown, a hydraulic telescopic component 44 for driving the slide plate 43 to move horizontally is fixed on the upper end surface of the fixed plate 41, and a pressure sensor 441 for detecting the squeezing force of the slide plate 43 is fixed at the output end of the pressure sensor 441, and the bottom of the pressure sensor 441 is fixed on the slide plate 43.

[0028] When the hydraulic telescopic component 44 is activated, it drives the slide plate 43 to move horizontally, causing the slide plate 43 to contact the workpiece. When the slide plate 43 contacts the workpiece, the reaction force of the workpiece is transmitted to the slider 47 through the slide plate 43. When the slider 47 detects that the reaction force is greater than the set value, the hydraulic telescopic component 44 stops operating, thereby effectively avoiding the problem of workpiece damage caused by excessive clamping force of the slide plate 43.

[0029] See Figure 3 , Figure 4 and Figure 6 As shown, a mounting groove 431 is horizontally opened at the center of the slide plate 43 and the side away from the slider 47. A rotatable bidirectional threaded rod 451 is installed inside the mounting groove 431. Two sets of clamping rods 46 for clamping the side of the workpiece are installed on the bidirectional threaded rod 451. The clamping rods 46 are threadedly engaged with the bidirectional threaded rod 451.

[0030] A servo motor 45 for driving the bidirectional threaded rod 451 to rotate is also fixed on the slide plate 43. The output end of the servo motor 45 is connected to one end of the bidirectional threaded rod 451.

[0031] When the servo motor 45 is started, it drives the bidirectional threaded rod 451 to rotate clockwise or counterclockwise. The rotation of the bidirectional threaded rod 451 drives the two sets of clamping rods 46 to move closer or further apart, thereby enabling the clamping rods 46 to clamp or release the workpiece.

[0032] See Figure 6 As shown, a sliding groove 432 for limiting the clamping rod 46 is symmetrically opened on one side of the sliding plate 43 near the mounting groove 431. A limiting block 461 that can slide along the slide groove 432 is provided on one side of the clamping rod 46.

[0033] To ensure the stability of the clamping rod 46, a limiting block 461 is provided on one side of the clamping rod 46. When the clamping rod 46 moves, it slides along the slide groove 432 through the limiting block 461, so that the limiting block 461 and the slide groove 432 cooperate to limit the clamping rod 46, thereby ensuring the stability of the clamping rod 46.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
